SPECIFICATION forming part of Letters Patent No. 663,503, dated December 1 1, 19O.

Application filed June 13,1899. Serial No. 720,383. (No model() To @ZZ 107mm/ zit may concern,.-

Be it known that I, GUSTAV G. LAUREYNS, a`

citizen of the United States,andaresident of New York, (Brooklym) in the county of Kings and State of New York, have invented certafin new and useful Improvements in Locks,

of which the following is a specification.

The invention relates to improvements in locks, and embraces the novel features hereio inafter described, and more especially designated in the claims.

My invention comprises, in general terms, two special features, one being a new lock construction and the second heilig the arrangement, relation, and construction of the features of a lock whereby in lnortise-locks the lock may be inserted into mere augerholes bored in the door to receive the saine.

The first feature ot' the invention comprises a number of novel elements capable of performing novel functions, and these Will appear in full in the detailed description hereinafter presented.

It is well known` that the application of mortise locks, latches, and bolts to doors could only be satisfactorilyaccomplished heretofore by skilled mechanics and with the aid of Ywood-chisels or other mortising-tools, and to overcome this inconvenience and expense lI have invented a mortise-lock embracing in concentrated form all of the desirable features and results of the latches, locks, and bolts heretofore known, as well as new features and results, and which, with all of its parts, is capable of heilig readily slipped into augerholes bored into the door to receive the same.

In carrying my invention into effect I have discovered that il' shafts or spindles in the form of keys or otherwise are inserted within and through the door-knobs and their spindles they can be used to accomplish in a superior manner the results which have ordinarily heretofore been performed in other locks and latches by means of separate han- .,5 dles, knobs, buttons, slides, thumb-pieces, and other accessories and in addition thereto will enable the accomplishment of other results not common to the locks and latches as heretofore made. `I have further discovered that when the said shafts or spindles or keys are thus made use of they can be made to fultil a number of purposes in accordance with the angle ordirection in which the same may be turned, and in this connection it is pref erable that indicating-marks be applied to the face of preferablythe inner door-knob,.

so that the user of the lock may be kept instructed thereby as to the correct position to which to turn the shaft or key when desiring to accomplish specific results.

The nature and objects of the invention, together With satisfactory means for carrying the same into practical effect, will appear in full in the detailed description hereinafter presented, taken in connection with the accompanying drawings, in Which-- Figure l is a central vertical longitudinal section through a lock constructed in accordance with and embodying the invention, a portion of the door being shown in vertical transverse section. Fig. 2 is a central vertical section of same on the dotted line 2 2 of Fig. l, the dotted line l l in Fig. 2 representing the section on which Fig. l is taken. Figs. 3, 4E, and 5 are detached elevations of certain tumbler-disks removed from the tumbler-cylinder of the lock and hereinafter designated by reference-numerals. Fig. 6 is a detached plan View of the outer escutcheon looking at the inner face thereof. Fig. 7 is a vertical longitudinal section of same on the dotted line 7 7 of Fig. 6.

Fig. 3l is a central vertical section of a modified form of the lock and its bolt, this modied construction being adapted for sliding doors. Fig. 32 is a detached side elevation of the `vertical section on the dotted line 34 34 of Fig. 31 of the lock adapted for sliding doors, and in this iigu re the dotted line 31 3l denotes the section on which Fig. 3l is taken. Fig. 35 is a detached outer face View of the inside escutcheon of the lock and showing in position the handle of the key, shaft, or spindle forcontrolling the position of the interiorgovernor, hereinafter described. Fig. 36 is a face view of the outside escufcheon of the lock; and Figs. 37 and 38 are detailed vertical sectional views through the bolt mechanism of the lock shown in Figs. 3l to 34, inclusive, the sections being on the dotted lines 37 37 and 3S 38, respectively.

I will first describe in detail the mechanism shown in Figs. 1 to 30, inclusive, and then specically refer to that illustrated in Figs. 31 to 38, inclusive.

In the description of the mechanism shown in Figs. 1 to 30, inclusive, I will first refer to the bolt, the plate or cog-wheel for actuating the saine, the inside escutcheon, and the inside knob, with their incidental features, since these elements in themselves comprise an operative combination and elnploy a portion of my invention.

In the drawings'the numeral 40 designates the bolt; 4l, the actuating-plate for coperation with said bolt; 42, the inside escutcheon, and 43 the inside knob.

The bolt 40 is shown in operative position in Figs. l and 2 and in detail in Figs. 14 and 15, in Which it will be seen that the bolt 40 in its preferred form comprises the head 44and shank 45, the said head being substantially circular in cross-section and the said shank being in the forln of a fiat plate provided with the guiding-slot 46 and at its opposite sides with the corresponding.studs 47 and camshaped st uds 48. The reason for the special construction of bolt shown will appear hereinafter.

The actuating-plate 4l for throwing the bolt 40 is shown in Figs. 1, 2, 8, 9, and l0 and is preferably formed at its upper 'and lower edges with the cogs 49 50 and at its ends with the upper and lower lever-arms 51 52, the said upper and lower edges being in every respect duplicates of one another and for purposes which will be hereinafter explained.

The actuating-plate 41 is preferably in one integral piece with the hollow hub 53, on which are formed the annular flange 54 and sleeve 55, the latter receiving the inner end ot' the tubular spindle or shaft 56, Fig. 1, upon whose outer end is secured the sleeve 57 of the inner knob 43, the jointbetween the sleeves 55 and 57 being covered by the sleeve 58 of the escutcheon 42, which is secured by bolts or screws 59 and at its inner end is formed with the shoulders 60 to form a suitable bearing within which the annular liange 54 on the hub 53 may turn and which vbearlOO TIO

ing serves to aid in supporting and guiding l` said hub 5o and the parts connected therewith.

In respect of the features above designated by reference-numerals itis to be observed that the turning of the knob 43 will result in the plate 4l receiving a partial rotary motion and the throwing of the bolt 40 by the engagement of the cogs 50 on the plate 4l with the studs 47 on one side ofthe upper edge ofthe bolt 40. While the cogs 49 at theupper edge ofthe plate 4l are of `great utility, it is sufcient for present purposes to simply refer to the lowercogs O,which, as shown in Fig. 2, act upon the said studs 47 of the bolt 40. The manual turning of the knob 43 may in accordance with its direction ot' motion throw the bolt 40 either outward or inward, and in the construction presented the bolt 40 may serve simplyas a latch or as a secure lockingbolt and has three motions-to wit, first, inwardly as a latch; second,outward automatically under the force of the spring l, Fig. 2, as a latch, and, third, a second or further outward motion as a bolt.

The spring 6l is a simple coiled spring pressing against the inner end of the bolt 40 to force the latter outward. A friction-spring G2, Fig. 2, is employed to steady the bolt 40 to prevent its too-free movement, and to hold the bolt when on its third movement above referred to its inner end passes outward from the influence of the spring 61.

The spring` (5l independently of any power applied to the knob 43 will permit the bolt 40 to have the inward and outward usual latch movements during the closing of the door (53; but when it is desired to open the door the bolt 40 is drawn inward by the manual turning of the knob 43. The third n10- tion of the bolt 40, orits further outward motion, results from the turning of the knob 43 sufficiently for the inner lever-arm 52 ofthe plate 4l to engage and press outward upon the inner camshaped stud 4S of the said bolt, whereby the said bolt may be drawn outward into the keeper 64, Fig. 20, about twice as far as when moved outward by the spring 6l as a latch. Thus the bolt 40 moves outward to one extent when used as a latch and to a far greater extent when used as a safety-bolt, and in the latter instance it will be observed that the bolt effectuallysecures the dooreven against the action of any prying-tool which might be used in an attempt to sp1-ing7 the door open. After the bolt40 has been moved outward to its fullest extent by the action of the knob 43 and that of the inner arm 52 against the inner lug 4S on the bolt the bolt must be moved inward again to its normal latch position by the turning of the knob 43 suiliciently 'for the outer lever-arm 52 of the plate 4l to engage and press inward against the outer cani-shaped lug 4S on the said bolt.

I may here explain that one reason for the special form ol bolt 40 presented with the studs 47 and 4S at opposite sides of its shank is that when constructed as shown the said bolt is reversible in four directions at will, thus rendering it adaptable for either a righthand outside latch, a right-hand inside latch, a left-hand outside lat-ch, and a lett-hand inside latch.

A very goed reason for having the upper and lower edges of the plate 4l correspond with one another is that the said plate is thereby rendered reversible, so that should the lower edge of the plate become worn by its frequent contact with the studs on the bolt 40 the said plate may be turned to bring its upper edge downward for direct coperation with said bolt.

With respect to the features above designated by reference-numerals I would callattention to the fact that I do not confine the invention thus far described to the throwing of the bolt 4() from the inside knob 43, since, as will appear hereinafter, the plate 4l and bolt 40 may also be operated from the outer side of the door by a key or other suitable turning medium.

In the present construction, Figs. l and 2, the lower screw 59 passes through the guideslot 46 of the bolt 40 and cooperates with said slot in guiding and sustaining the bolt. Upon the temporary removal of the said screw 59 the bolt 40 may be withdrawn from the door without disturbing any of the other parts of the lock, and this, I think, will be recognized as an advantage in lock mechanism.

Another advantageous feature may be here mentioned, and it is that simply la round auger-hole sulices to receive the bolt 40 and that another auger-hole 66 receives the parts above described for manually throwing the said bolt. rlhus the parts of the lock are so constructed and disposed with relation to one anotherl that when forminga mortise-lock they may be quickly and readily slipped into and secured within two auger-holes which an apprentice could quickly bore, instead of, as heretofore, with other locks requiring the service of a skilled mechanic to cut or chisel the mortise-recesses in the door. l

The auger-hole 65 will be of asiZe tosnugly receive the metal tubular socket 67, Fig. 2, for the bolt 40, andit is to be observed that this socket 67 has only its outer edge exposed and that this edge is very narrow, with the consequent advantage that upon the removal ot' the bolt. 40 the said edge may be readily filed down to any required bevel.

Having thus fully referred to one legitimate combination of parts in connection with the bolt 40 without going into the details of tumblers,keys,and other features which enter into the composition of the complete structure in its entirety, I desire to referto an element which may be adopted for one or more classes of locks and is actuated bythe aforesaid inner knob 43 or its equivalent and the plate 4l, and this element (shown more fully in Fig. 2) is the rod G8, which may be thrown outward by the plate 4l upon the turning of KCS the inner knob 43 in a direction to move theA bolt 40 inward. The head 69 of the rod 68 vwhen thrown outward enters the receivingaperture 70, Fig. 20, of a plate 7l, pivoted on the doorcasing and having a slot 72 leading from said aperture 70. The throwing outward of the rod 68 and the moving inward of the bolt 40, together with an opening force applied to the door, result in the outward turning of the plate 71 and the traveling along the slot 72 of the rod 68, whereby although the door may be opened somewhat it is prevented from opening beyond the length permitted by the slot 72, since the head 69 on the rod 68 is wider than said slot and prevents the slipping of the rod from the slot while the door is partly open. The rod 68 and pi voted plate 71 are of utility, and they form a desirable substitute for the usual chain placed on doors to prevent the latter from being fully opened by a force applied to the outer side of the door. The plate 7l being close against the door-jamb is practically invisible when the door is closed, and it need only to be used when desired, since, as will appear hereinafter, the rod 68 only moves outward to engage the plate 7l when the parts of the lock are manually set to permit that result.

The rod 68 need only move outward a distance a little greater-than the thickness of its head 69, and this movement is imparted to it by the inner upper lever-arm 51 on the plate 4l coming into contact with and exerting outward pressure on the stud 73, Fig. 2, on the sliding bar 74 after the latter has been tilted upward, (bythe means hereinafter described,) so that its upwardly-extending inner end may during the outward movement of said bar 74 press outward upon the inner end of the said rod 68 and drive said rod outward and its head 69 into engagement with said plate 71. During the ordinary turning of the plate 41 the bar 74 will slide freely within its socket without affecting the rod 68, since under normal conditions the inner end of said bar 74: will pass below the rod 68; but when the bar 74; is tilted upward by the said means to be hereinafter described, its inner end is compelled, during the outward movement of the bar, to meet and press outward against the inner end of the rod 68. The front or outer end of the bar 74 carries a guiding-head 75, and through an aperture in this head the rod 68 freely passes, as shown. The springs 76 and 77 serve to withdraw the sliding bar 74 and rod 68 into their socket in normal position, and upon the closing of the door after the turning outward of the plate 7l the plate 71 turns upward and inward again, and the springs 76 and 77 relieve the head 69 of said rod 68 from said plate, and thereupon, if desired, the door may be fully opened. The rod 68 may.slide freely through the stop-plate 78 for the springs 76 and 77, and the rod 79, carrying the spring 76, is stationary and the inner end of the bar 74 may slide freely upon it.

In the foregoing description I have not referred to keys or tumblers, since the actuating-plate 41 may be operated, as we have seen, from the inside knob or its spindle, or anything else, such as a key, for turning the said plate 41, but in the further description of the lock as an entirety I will refer to the tu mblers, the outside knob, the keys, and the governor.

The governor,asIhave termedit, should first be referred to, since it is more directly connected with the parts hereinbefore specifically described,and this governor (numbered 80) is shown in detailin Figs. 16 and 17 and in its operative position in Fig. 1, in which it will be seen that the bifurcated shank 81 of said governor enters and is revoluble within a sleeve 82, secured within the aforesaid hub 53, carrying the plate 41. The bifurcation of the shank 81 is to receive the point of a key 83, Fig. 1, inserted directly through the knob 43 and tubular spindle 56. The governor 8O is preferably of oval shape, as shown in Fig. 16, and is formed at its narrower end with the biting recess 84. The governor 8O in its various positions to which it may be turned by the key 83 controls cer' tain features and operations of parts of the lock which have not thus far been described, and hence the special functions of the said governor will be pointed out in an appropriate place hereinafter. The said governor 8O simply has a turning action under the influence of the key 83, and this key may be of any suitable construction and is always inserted into the lock from the inner side of the door. I have provided a series of slotted plate-tumblers 85 for the key 83, so as to com pel the use of the proper key and in the proper manner; but the feature of the tumblers 85 I do not regard as of great importance, and they may be varied at will in ways well-known to those skilled in the art, or they may be entirely omitted.

The removable key 83 need only be used when the lock is located in doors which separate rooms, such as in a hotel, and when a removable key 83 is not necessary for the turning of the governor 8O I shall have the said governorsecured upon a permanent shaft 239, Fig. 29, extending through the tubular spindle 56 of the knob 43 and having a pointer or arrow-shaped handle 238, by which said governor may be turned in the same manner and for the same purpose that it is turned, Fig. l, by the handle of the key 83. The shaft 239, Fig. 29, has the same operation as the key 83, Fig. 1, upon the governor 80, and the handle of the key 83 has a. pointer end, the same as the handle 238 for the shaft 39, said pointer end being used in connection with the series of indicator-marks, Fig. 28, on the knob 43 to guide the user in turning the shaft 239 or key 83 to the proper position for effecting the various results to be accomplished, as hereinafter pointed out, by the setting of the governor 80.

IIO

Substantially all ot the features connected with that hall ot the lock located toward the inner side oll the door having been hereinbefore described, I will proceed to describe those features'of that halt of the lock located toward the outer side ot the door.

The outer knob is designated bythe numeral 86, and it is mounted on the outer end of a tubular spindle 87, through which (and said knob) the outer key 88 is to be passed, Fig. 1, for unlocking the door. rllhe outer escutoheon 89 is held in place by the screws 59, and its details of form and consti-notion are shown in Figs. 6, 7, 21, and 22. The outer escutcheon 89 is very similar to the inner escutcheon 42, but has the slotted arms 90 and 91 and spring 92, the latter being in the present instance sim ply a leaf-spring at one end hooked upon the arms l90 and extending from the said arms 90 to the arms 91, between which its effective portion, bent into loop form, is located, the said effective portion of said spring forming a spring-catch 237 for looking the tumbler-cylinder 93 in a normal position, as will appear hereinafter and as is shown in Fig. 22.

Upon the inner end of the outer knobspin dle 87 is secured the tumblei-cylinder 93, whose sleeve 94 is directly upon said spindle, as shown in Figs. land 21. The details of the cylinder 93 are illustrated in Figs. 11, 12, 13, and 21, in which it will be seen that the cylinder is hollow, that it cout-ains the series of longitudinal radial slots 95, that its face has 'formed in it the annular recess 96, and that its periphery bears the annular shoulders 97 and 98 and the annular groove 99. Within the recess 96 is placed a disk-plate 100, Figs. 1 and 22, to close the inner end of the chamber formed within the cylinder 93, but not filling said recess, which, as shown in Fig. 1, receives the governor 80, hereinbefore described. lVithin the annular groove 99 of said cylinder 93 is placed a band-spring 101, which is simply a strip of spring metal wrapped into said groove, but at no point rigidly fastened to said cylinder 93. The spring 101 is more clearly shown in Figs. 1, 21, and 30 and is in the nature of a section of clockspring. )Vitliin the slots of the cylinder 93 are placed a series of plate-tumblers 102, 103, 104, and 105 (shown in Figs. 23, 24, 25, and 20,) and which are held normally inward within the slots 95 by the spring 101, located within the annular groove 99 of said cylinder 93. The tumblers 102 to 105, inclusive, in operation are adapted to move radially within the slots 95 and to be independently set in motion or moved outwardly radially by the governor 80 in the manner and for the purposes hereinafter explained. The tumblers 102 and 103 extend outward from the inner vertical t'ace ot' the cylinder 93 to or nearly to the inner vertical face ot' the actuating-plate 4l, so that during the rotary motion of said tumbler-cylinder 93 (under the action of the tumblers 102 and 103 will move against the end ot the shoulder or shoulders on the face of said plate 41, Figs. 2,9, and 10, and communicate the motion of said cylinder 93 to said plate 41, with the purpose ot causing the latter to move the bolt 40 into the socket and freeing the door. The tumblers 104 and 105 at their outer ends are flush with the vertical end tace of the cylinder 93.

The tu m blers 102, 104, and 105 are normally Hush with the outer horizontal edges of the slots 95; but the tumbler 103, as shown in Fig. 22, is normally set inward from the outer horizontal edge ot' the slot 95, thereby leaving a portion of said slot to be occupied by the spring-catch 237, which by engaging said slot automatically retains the tumblercylinder 93 and outer knob 86 in a normal proper position at rest and prevents the turning of the outer knob except when the proper outer key 88 is used or the governor 80 is so set as to permit of said outer knob being turned, as when the entire mechanism is transformed into a latch operable from either knob.

The tumbler 102 differs trom the tumblers 103, 104, and 105 in that it carries on its inner end the slotted key-plate 107, Fig. 23, which extends inward and is located at or near the base of the set of irregular disktu mblers 108, Fig. 1, inclosed within the chamber formed by the cylinder 93 and slotted to receive the outer key 88 and conform to the wards thereof. Then the cylinder 93 is in a normal position at rest, the tumbler 102 will be in alinement wit-h the slot between the arms 90 of the outer escutcheon 89, and when the said tumbler is pressed radially outward and there held by the governor 80 its outer edge will pass between said arms 90, and its plate 107 will be withdrawn from alinement with the key-slots in the tumblers 108, and under such condition the key-cylinder 93 would be prevented from turning at all and even the proper key 88 could not be introduced into the interior of the cylinder 93.

The tumblers 102, 103, 104, and 105 are each capable of being moved outward by the gov.

ernor 80, and when released by said governor said tumblers move inward under the action of the spring 101. The tumbler 103 is also, under the action of the outer key 88, capable of being moved outward until its outer edge is flush with the o uter horizontal edge of its slot 95, this being for the purpose of causing it to press the spring-catch 237 from said slot and in that manner free the cylinder 93, so that it may be turned and the door opened. Vhen the key 88 is used to move the tumbler 103 outward to free the catch 237 trom the cylinder 93, said key operates to turn the protruding or cam-shaped edge, Fig. 3, of one or more of the tumblers 108 against the inner edge ot' said tu mbler 103, and thereby effects the desired result.

ders 204 and arms 90 and 91 of the outer escutcheon and turns within the same, said shoulders and arms serving as a bearing for said cylinder. The lower shoulder 204 has in its upper edge a recess 109 to receive and engage the lower horizontal edge of the tum bler 104 when said tumbler, as hereinafter described, is pressed downward by the governor 80.

In the full use of the complete lock shown it is essential that the tumbler-cylinder 93 return to its normal at-rest position and be there caught every time the door is opened from without, and to this end I provide a spring 110, Figs. 21 and 27, which encircles the sleeve 94 of said cylinder and is doubleacting, so as to restore the cylinder 93 to its normal position whether the knob 86 is turned to the right or left on opening the door. The spring 110 has its two ends brought substantially together upon opposite sides of the pins 111 and 112, the former being carried by the cylinder 93 and the pin 112 being rigid with the escutcheon S9. The pin 111 will, when carried in one direction by the cylinder 93, draw on one end of the spring 110 and place the latter under proper tension and when carried in the reverse direction will draw on the other end of the spring 110 and again place the same under proper tension, the stationary end of the spring being meanwhile held by the pin 112. The spring 110 is employed to restore the cylinder 93 to its normal at-rest position, and upon reaching that position it (said cylinder) is automatically caught and held by the springcatch 237, which following the surface of the annulai` flange 98 of the cylinder 93 springs into the slot 95 for the tumbler 103 as soon as said slot reaches said catch.

The outer knob S6 will preferably be hollow and provided with a hinged cap or outer section 113, Fig. 1, which when pressed to closed position will snap upon the other section of the knob, the purpose of the cap 113 being to exclude dust or other foreign matter from the key slot or opening.

The features connected with and composing that half of the lock toward the outer side of the door have now been described, and I will proceed to an explanation of the operation of the lock as a whole, giving particular reference to the governor 80, whose position is wholly controlled by manual operation from the inner side of the doorand regulates the performance of many of the useful functions of t-he lock.

It will be observed on reference to Fig. 1 that the inner half of the lock and the outer half of the lock are each in one connected set of mechanism carried by the knobspindle and that these two halves or sets of mechanism are simply inserted into the auger-hole 66 from opposite ends of the latter and brought together, being then secured by the screws 59 and the governor 80 entering the recess 96 of the tumbler-cylinder 93 and the projecting ends of the tumblers 102 103 reach- First. Let us suppose that the governor has been turned directly upward, so that its 4 projecting end has pressed upward the tumbler105, the latter being then in line with the slight recess orgroove 84 of said governor. Under this condition the tumbler 105 will have moved against and tilted upward the bar 74, located over the actuating-plate 41, and the hold-rod 68 may be brought into use, and upon the turning of the inner knob 43 to draw the bolt 40 inward the rod 68 will be moved outward to engage the hold-plate 7l, with the result that the door may first be opened a short distance under the protection of said rod and plate and then closed. If it should then be desired to open the door fully,

the governor S0 will be turned to an inopera- A tive position intermediate the tumblers 102, 103, 104, and 105, whose positions are indicated by the markings on the door-knob 43, Fig. 2S.

Second. Should the governor 80 be turned against the tumbler 103, so as to press said tumbler outward, and thereby exclude the spring-catch 237 from the tumbler-cylinder 93, the outer knob 86 becomes eifective to withdraw the bolt 40 as a simple latch-bolt, no outer key being required. Under this condition the projecting ends of the tumblers 102 103 engage the shoulders 106 of the plate 41, and the latter on being turned thereby will actuate the bolt 40.

Third. Should the governor 30 be turned directly downward against the tumbler 104, it will drive a portion of said tumbler into the recess 109 of the shoulder 204, Figs. 1, 6, and 22, and another portion of said tumbler intermediate two of the studs on the bolt 40, thus working two results, one being the locking of the cylinder 93 against rotation by any means and the other the locking of the bolt 40 stationary, whether' at the time it be either inward or outward. If at this time the bolt should be inward, it will be there locked, and the door may be left unrestrained, so that there will be no danger of its latching even if it should close. It', on the other hand, the bolt 40 should at this time be in either of its outward positions, it will be there locked and cannot be unlocked either from the inside or outside of the door except after the governor 80 has been turned from said tumbler 104. At night the bolt 40 should be moved to its full outward safety position and be there locked by the engagement of the governor 80 with the tumbler 104. y

Fourth. When the governor 80 is turned to press the tumbler 102 outward into the slot IOO IIO

ees, 50e

between the arms 90 of the escutcheon S9, the cylinder 93 is held against allturningaction, and neit her the outer knob or outer key can operate the bolt 40, and in addition, it' the tumble:I 102 is furnished with the key-plate 107, Fig. 23, even the proper outer keyis excluded from the lock.

Fifth. Should the governor be turned to any position intermediate the points denoted by the tu mblers 102, 103, 104, and 105, it would be out of operation and the bolt 40 could be operated from the inside knob or by the outer key 3S, but not from the outside knob alone,

since the spring-catch 237 would then hold.

the tu mbler-cylinder 93 and outside knob S0.

If it should not be desired to employ the hold-rod GS and plate 71, the tumbler 105 could be omitted entirely, and then when the governor S0 was turned upward it Would be in an inoperative position. It is my purpose to only use such of the tumblers 102,103, 104, and 105 as may be necessary to secure the results it is desired the lock shall accomplish.

In some instances the outer key S8 would not be necessary for use and in such cases the outer knob S6 would be simply a solid knob. The governor S0 would even in such cases be retained, so that it might be used to render ineffective the outside knob, to lock the bolt 40 in either of its positions, and to bring into use the hold-rod 68.

The tuniblers S5 for the inside key S3 and the tumblers 103 for the outside key 8S will vary at will. The form of the tumblers 102, 103, 104, and 105 may also vary in many respects, and the present invention is not limited to the shape of these tumblers nor to the number ot' them which may be employed.

In Fig. 1 1 illustrate the invention as embraced in a lock having projecting doorknobs; but 1 do not limit the invention in every instance to the employment of projecting doorknobs, since there are many in stances in which it may be desired to so construct and concentrate the part-s of the lock that the knobs shall not project beyond the sides of the door-as, for illustration, in the case of sliding doors. In order, therefore, that my invention may be more fully understood, 1 illustrate in Figs. 31 to 3S, inclusive, a construction ot' the lock adapted for sliding doors, the feature of introducing the parts of the lock into mere auger-holes formed in the door being preserved. 1n Figs. 31 and 34 the door is denoted by the numeral 63, and this door, corresponding with the door shown in Fig. 1, is formed with the auger-hole 6G for the lock mechanism proper and with the auger-hole for the socket for the bolt. In Fig. 34 it will be observed that at the outer and inner sides of the door (33 are secured within the outer edges of the auger-hole 60 the esculcheons 120 and 121, these escutcheons being in the form of iush cups and secured together by means of the screws 122. l'fVithin the inside escutcheon 120 is arranged the knob 123, which is in the form of a plate or disk having thumb-pieces 124 tofacilitate its manual operation. Upon the hub of the disk knob 123 is secured the actuating-plate 4l, corresponding in all respects with the actuating-plate 41 (shown in Fig. 2) for engaging the bolt. l/Vithin the hub of the disk knob 123 is placed the shaft 125, having at its outer end the handle 126 and at its inner end carrying the governor 80, corresponding with the governor provided i'n the lock shown in Figs. 1 to 23, inclusive.

The outer knob 127 ot the lock shown in Fig. 34 corresponds with ihe'disk inside knob 123 and is provided with the finger-pieces 128 to vfacilitate its manual operation. The outside knob 127 is formed with the key slot or opening 129 for the outer key 130, and said outer knob 127 will preferably be formed in one piece with the tumbler-cylinder131,Which corresponds substantially with the tumblercylinder shown in Figs. 11, 12, and 13, and will be equipped With the inside plate or disk tumblers 10S, the radial tumblers 102, 103, and 104, and the band-spring 101 for said radial tumblers. The tumbler-cylinder 131 (shown in Fig. 34) may also, if desired, be provided with the radial tumbler 105 (shown in Fig. 22) should any occasion arise for the use of said tumbler. In instances in which the upper hold-rod 68 is not present the upper tumbler 105 need not be employed. The details of the tumblers of the tumbler-cylinder 131 (shown in Fig. 34) need not be specifically described at this place, since they correspon d in every respect withthe tu m blers hereinbefore described with respect to lthe lock shown in Fig. 1. My main purpose in illustrating the modification shown in Figs. 3l to 3S,inclusive, is to make it plain that the lock may be adapted for sliding doors and that the invention is not confined to all of the details shown in Figs. 1 to 30, inclusive. The governor 80 (shown in Fig. 34) has the same operation ascribed to it with respect to the lock of Fig. 1, and hence the operation of the knobs, key, and governor shown in Fig. 34 will be understood without further specific description.

The bolt shown in Figs. 31 and 32 diiiiers in construction from the bolt shown in Fig. 2, the change being rendered necessary by the fact that the holt of Figs. 31 and 32 is intended t'or sliding doors instead of hinged doors. The bolt shown in Figs. 31 and 32 comprises the exterior shell 132, the latchplate 133, and the auxiliary latch-plate 134, both ot' said latch-plates being held Within said exterior casing 132 on a pivot or pin 135, which is rigid with the latch-plate 133 and enters a free aperture in the plate 134. The main latch-plate 133 c'ontainslthe cam-slot 136, through which passes the stationary pin 137. Within the shell 132 is also provided the spring 133, which exerts a normal upward tension to throw the outer ends of the latchplates 133 and 134 in directions opposite to one another, so that they may when in their IOC IOS

IIO

outward position engage the upper and lower edges of the keeper on the door-casing, as shown in Figs. 3l and When the bolt of 3l and 32 is drawn into its socket within the door, the outer ends of the latch-plates 133 and 134 will be held by the confinement of the said socket int-o the closed position illustrated in Fig. 33. The upper edge of the latch-plate 133 will be formed with a shoulder 139, against which one of the cogs or projections 50 on the actuating-plate 41 may strike when turned downward, and thereby depress the outer end of the latch-plate 133, and consequently the latch-plate 134, into alinement with the socket for the bolt. In Fig. 31 the bolt is shown in its outer posi tion, and should it be desired to open the door 63 the actuating-plate 41 will be turned to cause its cog or projection 50 to press downward against the shoulder 139 of the latchplate 133, there by closing the front ends of the latch-plates 133 and 134 together, as shown in Fig. 33, and thereupon the continued turning motion of the actuating-plate 41 will cause the arm 52 of said plate to meet the rear end of the casing 132 and move said casing and the then closed latch-plates inward into their socket. During the inward motion of the bolt shown in Fig. 31 the edges of the camslot 136 riding on the pin 137 will operate to retain in their closed position and even to more closely close the latch-plates 133 and 134. During the outward motion of the bolt shown in Fig. 31 the camslot 136 riding on 1 the pin 137 will allow the front portions of the latch-plates to gradually separate and finally become free, so that they may assume under the force of the spring 13S the position they occupy in Fig. 31. The actuating-plate 41 is utilized in the construction shown in Fig. 31 to throw the bolt both outward and iuward, and the invention is not confined to the bolt shown in Figs. 31 and 32, this bolt having been shown merely to illustrate the main portion of the invention in its adaptation to sliding doors.

The various features of the invention have been so fully described hereinbefore that it is not believed that a further detailed description of the construction or operation of the parts of the lock is necessary.

I desire it to be understood that the in vention in its broader scope is not coniined to details of form or construction and that the form and construction of the parts hereinbefore described may vary in. many Ways without departing from the spirit of the invention. I have referred to one or two modifications of some of the parts of the lock; but it will be understood that the parts ot the lock may be, varied'in other particulars at will in order to adapt the lock for different conditions and classes of doors and the par ticular results sought to be accomplished by means of the invention. For instance, a flush-cup escutcheon might be employed at one side of the door and a projecting knob at the other side thereof; or the inside knob might be omitted altogether and only the handle of the governor 8O appear at the inner side ol the door, the indicatoirnarks for the several positions of the governor being placed on au escutchcon surrounding said handle, or the outside knob might be omitted and the outside key passed through the face of the outside escutcheon.
